PARASITIC HYMENOPTERA FROM THE SIKKIM HIMALAYA. 91 



Fenenias alhomaculatus Cam. 



Common, as it is in the Khasias. 



Phygadeuonini. 

 Sogna gen. nov. 



Scutellum roundly convex, its sides stoutly keeled. Median 

 segment areolated, shining, for the most part punctured or 

 striated. Transverse median nervure in hind wings angled and 

 broken near the bottom. Antennae 25-jointed, the 1^*^ joint of 

 flagellum fully 3 times longer than thick, clearly shorter than 

 the 2'"^ ■ Petiole wide, becoming gradually wider from the 

 middle to the apex, curved. Pace not separated from the clypeus 

 by a farrow ; the latter broadly rounded at the apex. Temples 

 very short. Parapsidal furrows only indicated at the base. 

 Disco-cubital cellule at base nearly twice the width of the 

 2"d discoidal cellule at apex. 



Malar space long, as long as the antennal scape. Areolet 

 large, 5-angled. Transverse median nervure received shortly 

 behind the transverse basal. Areola large, semicircular, the 

 petiolar confluent with the lateral areae ; the dorsal keels of 

 1st abdominal segment not reaching to the spiracles. The abdo- 

 minal petiole at apex is four times the width of the base. 

 There is a large closed area on the lower side of the meta- 

 pleurae ; the upper keel is broadly, roundly curved upwards ; 

 the lower roundly curved downwards at the base. Gastracoeli 

 wide, the S^''^ segment is depressed and crenulated at the base ; 

 the apex of the abdomen is bluntly rounded. Ovipositor not 

 projecting. The radius originates from the middle of the stigma. 

 Recurrent nervure with 2 bullae. Antennae stout, short, not, 

 or hardly, narrowed towards the apex. Metathoracic spiracles, 

 distinct, about two and a half times longer than wide. Parallel 

 nervure in the middle of the brachial cell ; the discoidal cell
